FUNCTIONAL DEVICE OPERATION
LOGIC COMMANDS AND REGISTERS
ON /OFF CONTROL COMMAND
To program the 8 outputs of the 33800 ON or OFF, a 16-
bit serial stream of data is entered into the SI pin. The first 8-
bits of the control word are used to identify the on / off
command and the remaining 8-bits are used to turn ON or
OFF the specific output driver. When commanding an output
ON or OFF, the Most Significant Bit (MSB) is sent and
received first. Bit 7 corresponds to output 8 down to bit 0
which corresponds to output 1.
OPEN LOAD CURRENT ENABLE COMMAND
The Open Load Enable Command is provided to enable or
disable the open load detect pull-down current. This feature
allows the device to be used in LED applications. On power
up reset (POR) or the RESET command the pull-down
current sources are disabled. To enable the open load
current source, the user must program the Open Load
Current Disable Control register with logic[1]. Open load
faults may not be reported with the pull-down current source
disabled.
OVER-VOLTAGE SHUTDOWN/RETRY COMMAND
The Over Voltage Shutdown/Retry Command allows the
user to select the fault strategy for the outputs. The over-
voltage control bit sets the operation of the outputs when
returning from over-voltage. Setting the over-voltage bit to
logic[0] will force all outputs to remain OFF when V
PWR
returns to normal level. Setting the over-voltage bit to logic[1]
will command outputs to resume their previous state when
V
PWR
returns to normal level.
TLIM COMMAND, TIMER COMMAND
The TLim and Timer commands are used to enhance the
short circuit protection strategy of the Octal Serial Switch
output drivers.
The Timer protection scheme uses a low duty cycle in the
event of a short circuit. The TLim protection circuit uses the
